This study aims to develop an index of food security in order to assess food security status in Korea and to evaluate reliability and validity of the index. The index of food security was developed based on the US Household Food Security Survey Module (US-HFSS). After the US-HFSS was translated and back-translated, it was evaluated and modified by a focus interview for experts. The developed Korean Household Food Security Survey Module (K-HFSS) was tested by cognitive interviews and a pretest for general community population to assess its application for Korean population. For the reliability and validity of K-HFSS, the survey was conducted with 300 adults aged 40 years or more living in a rural community and 212 infants and toddlers living in an urban community. The reliability was assessed by Cronbach' alpha and the validity was evaluated by content validity, construct validity, and criterion-related validity. The questionnaire items of K-HFSS were partly modified, accounting for Korean social and cultural backgrounds and adapted by general community population. The reliability was relatively high, showing Cronbach' alpha coefficients ranged from 0.80 (for adults) to 0.87 (for infants and toddlers). The content and construct validities were all acceptable. The result of criterion-related validity showed that food security status was significantly related to the household income level. In conclusion, the K-HFSS would be used as a reliable and valid instrument to assess food security status in parts of the Korean population.

The purpose of the study was to determine the convergent validity, discriminant validity and internal consistancy reliability of the social support and family support measuring tool. Two procedures were used : 1) Campbell and Fiske's multitrait-multimethod approach and item total correlation with Chronbach's $\alpha$. The result suggest that SNM, NSSQ, SNM/family, NSSQ/famliy is a valid and a reliable instrument for measuring social support. But PRQ part2 is low in convergent validity. The results further suggest that we have to more attention to a valid and reliable likert type scale for social support.

의료정보이해능력을 평가하는 것이 매우 중요한 시점이 도래함에 따라 이를 위한 다양한 측정도구들이 개발되어 오고 있다. 그러나 적절한 한국어판 측정도구 개발에 대한 논의는 활발하지 못한 실정이다. 본 연구에서는 5점 척도로 구성된 한국어판 REALM (rapid estimate of adult literacy in medicine) 측정도구를 제안하고 타당성에 대해서 알아보았다. 그 결과 5점 척도로 구성된 한국어판 측정도구의 신뢰도는 매우 높으며, 인자분석 결과 단일차원을 형성함을 알 수 있었다. 그리고 2점 척도에 비하여 긍정적인 응답이 적게 나타났으며, NVS (the newest vital sign)와의 상관계수를 구해본 바 통계적으로 유의하게 나타났다. 이에 5점 척도를 이용한 한국어판 REALM은 타당한 측도임을 알 수 있었다. 마지막으로 의료정보이해능력에 대하여 일반학생과 간호학과 학생 간에는 통계적으로 유의한 차이가 있었다.

Objectives : To introduce and compare various headache measurement tools, in order to provide fundamental information for future clinical trials and development of oriental medicine measurement tools. Methods : Eight headache assessment scales, Migraine-Specific Quality of Life Questionnaire(MQoLQ), Migraine-Specific Quality of Life(MSQOL), Migraine-Specific Quality of Life Questionnaire(MSQ), The Headache Impact Questionnaire(HImQ), Headcahe Needs Assessment Survey(HANA), Henry Ford Headache disability Inventory(HDI), Migraine Disablity Assessment Scale(MIDAS) and Headache Impact Test(HIT-6), were searched through Pubmed. General character, the process of development, verification of reliability, internal consistency, responsiveness to patient's change and validity were reviewed. Results : In assessing the quality of life of migraine patients, MQoLQ can be used to measure the change within 24 hours, MSQ and MSQOL can be used to measure the change during a relatively longer period of time. The frequency and bothersomeness of headache can be easily measured by HANA. HImQ can be used to measure the intensity of headache and the influence on normal daily activities. HDI can measure the emotional difficulties of headache patients. HIT-6 and MIDAS makes measurements possible in a short period of time, and the reliability and validity have been verified numerously. HIT-6 and MIDAS are the most frequently used measurement tools because they are simple and easy for both the assessor and the patient to understand and use. Conclusions : In this study, various headache assessment tools have been reviewed. The assessed tools were widely used after being verified for their reliability and validity. We hope this study provides fundamental information in establishing future clinical trial and clinical practice guidelines. We also hope this study to contribute to the development of an oriental medicine assessment tool for headache.

The purposes of this study were to examine the reliability and validity of Korean translation of Pediatric Evaluation of Disability Inventory (PEDI-K) in school-aged children with cerebral palsy (CP). The PEDI-K, Functional Independence Measure for Children (WeeFIM) and Gross Motor Function Classification System (GMIFCS) were completed in 104 school-aged children with CP by therapists. The internal consistency of the PEDI-K was calculated by Cronbach's alpha (${\alpha}$) for assessing reliability. Concurrent validity was evaluated by correlation with the subsets of WeeFIM. Discriminant validity was assessed by comparing GMFCS levels with tests of the PEDI-K. The results showed that internal consistency was good (Cronbach's ${\alpha}$ ranged from .97~.98). Concurrent validity was demonstrated. The correlation with WeeFIM was high in the Functional Skills (self-care, r=.74~.94; mobility, r=.59~.91; social function, r=.65~.93) and in the Caregiver Assistance (self-care, r=.75~.94; mobility, r=.63~.90; social function, r=.78~.96). Discriminant validity was demonstrated on significant decreases in domain scores with increasing GMFCS levels. Reliability and validity have been demonstrated on the PEDI-K. This study extends usage of PEDI-K in clinical activities and research.

PURPOSE: The Western Ontario and McMaster Universities Arthritis (WOMAC) index has been used to measure the outcome of total knee replacement (TKR), but studies on its reliability and validity are limited. The present study examined the reliability and validity of this index for patients with knee osteoarthritis who underwent TKR. METHODS: Seventy-one inpatients and outpatients who underwent bilateral TKR for knee osteoarthritis were included in this study. The pain assessment scale and WOMAC index were used to evaluate the participants every two weeks to examine the test-retest reliability, internal consistency, and construct validity. RESULTS: The test-retest reliability scores for pain, stiffness, and physical function were .75-.92, .85-.90, and .75-.95, respectively. The corresponding intraclass correlation coefficients were .75-.88, .76-.88, and .71-.95, respectively. The internal consistency score in the first and second examinations was .92. Furthermore, the construct validity scores for pain, stiffness, and physical function were .83, .41, and .58, respectively. CONCLUSION: The application of the WOMAC index in patients who underwent TKR showed high test-retest reliability and internal consistency with the use of the WOMAC index and good validity with the use of the pain assessment scale.

Purpose: Climate change has various negative effects on human health, which has resulted in increased burden on the health care system. Nurses contribute significantly to assessing climate-related health risks and creating a healthy environment. This study aimed to evaluate the reliability and validity of the Korean version of the Climate, Health, and Nursing Tool (K-CHANT) to measure nurses' awareness, motivation, concern, and behaviors at work and at home regarding climate change and health. Methods: The 22 items of English CHANT were translated into Korean with forward-backward translation techniques. Internal consistency reliability, test-retest reliability, and construct validity using confirmatory factor analysis were performed using SPSS WIN (25.0) and AMOS (26.0). Survey data were collected from 220 master's, doctoral, and post-doctoral nursing students. Results: The K-CHANT consists of 20 items across 5 domains. Two items of the original CHANT were excluded because of low content validity index and standardized regression weights. The internal consistency reliability of the K-CHANT, assessed by Cronbach's α was .81, with an intraclass correlation coefficient of .66~.90. The five subscales model was validated by confirmatory factor analysis (SRMR < .08, RMSEA < .08, AGFI > .70, CFI > .70). Conclusion: The K-CHANT has satisfactory construct validity and reliability to measure nurses' awareness, motivation, concern, and behaviors at work and at home regarding climate change and health. Future research should examine nurses' perceptions and behaviors related to the health effects of climate change and develop an action plan to improve it.

In the present study I developed the test for earth scientific creativity level and verified means to measure scientific creativity. I developed 22 test items and after being examined by science education specialist, 11 items were finally established, and these were applied to 104 middle students. Each answer paper was graded according to the standard answer that I developed and the results of analysis are as follows. First, to verify the validity of measuring means I figured out content validity. The content validity about test items and adequacy of evaluation goal was examined by 1 science education specialist and 3 middle school science teachers, 6 education graduate students. As a result of validity verification, the content validity was 82.7% and it showed that the test of earth scientific creativity was valid for evaluation goal and sub-factors of creativity. Second, to verify reliability of measuring means, I analyzed internal consistency of the test sheet of earth scientific creativity after finding correlation coefficient and Cronbach's $\alpha$. Cronbach's $\alpha$, the internal reliability coefficient, was 0.848. Therefore, it was verified that this test sheet of earth scientific creativity is reliable to measure the creativity of the middle school students. The correlation between sub-factors of creativity was statistically significant, and for the relation between the variables related to creativity, the originality was the most significant. This shows that in the procedure of scientific creativity and studying science, originality should be the most important factor.

Objectives: We developed a Korean translation of this questionnaire by sequential forward-and-backward translation. The purpose of this study is to validate the Korean version of the POEM, the "POEM-K" by Korean patients with atopic dermatitis (AD). Methods: A single-center prospective study was conducted with 50 participants diagnosed with AD. The POEM was translated to Korean version by an expert panel. Scoring Atopic Dermatitis (SCORAD) and Short Form 36 Health Survey (SF-36) were used as external comparators. Results: Twenty men and thirty women between the ages of 18 and 63 participated in the study. The test-retest reliability of the total POEM-K was estimated using the intra-class correlation coefficient (ICC) that showed a strong agreement (ICC = 0.72). By using Pearson correlation coefficients, we compared the POEM-K to SCORAD and yielded a concurrent validity that showed a significant result. The responsiveness of the POEM-K was represented by the effect size (ES) of 1.41 and statistically significant (p = 0.004). Conclusions: The Korean version of the POEM is a reliable, valid, and responsive disease-specific questionnaire for assessing the symptoms and quality of life of Korean patients with AD.
